Disclosed is an anti-reverse rotation device of a power-driven shoe device, the power-driven shoe device comprising a shoe sole (1), wherein a group of front wheels (2) and a group of rear wheels (3) are arranged on a lower side surface of the shoe sole (1); and the front wheels (2) are connected to an anti-reverse rotation mechanism for preventing the front wheels (2) from rotating in reverse. The anti-reverse rotation mechanism can prevent the front wheels (2) from rotating in reverse, and as such, when the front wheels (2) are independently in contact with the ground and a certain included angle is formed between a shoe body and the ground, the situation of the front wheels (2) applying a certain pressure to the ground and the front wheels (2) rotating in reverse, such that a lifted foot moves backwards, thereby causing a person to fall down, is avoided, and walking safety is improved.

Disclosed is an adjustment mechanism for an electric power-driven shoe, the mechanism comprising a shoe sole (1), wherein a plurality of rolling wheels (2) are arranged below the shoe sole (1); a foot-positioning mechanism is arranged above the shoe sole (1) and is provided with an angle-adjusting mechanism for adjusting an angle between the foot-positioning mechanism and a lengthwise direction of the shoe sole (1).
